Atomic masses<span> :

N =14 a.m.u
H = 1 a.m.u
O =16 a.m.u
Therefore:
( NH₄)₂O = (14 * 2) + (1 * 4 *2) + (16* 1) => 52.0 g/mol
Im not sure but i think its hbr. i hope im right and i hope this helped,
Answer:
number of dozens = 4.35834 * 10^21 dozens
Explanation:
A dozen contains 12 atoms. To know the number of dozens containing
5.23 * 10^22 atoms, all we have to do is cross multiplication as follows:
1 dozen ...........> 12 atoms
?? dozens ......> <span>5.23 * 10^22
number of dozens = (</span><span>5.23 * 10^22 *1) / (12)
number of dozens = 4.35834 * 10^21 dozens
Hope this helps :)</span>
The two angles would be both 41 degrees.
x in this case would be 14 degrees.
